According to Toms Hardware the APU is expected to be the younger brother of AMD’s Phoenix.
The supposed Phoenix 2 processor die shot clearly shows a large L3 cache, two high-performance Zen 4 cores, four smaller Zen 4c cores, and a large built-in GPU.
There are several DDR5/LPDDR5 PHY interfaces on top of the die, as well as PCIe, USB, and other physical interfaces on the APU’s bottom and left and right sides of the APU.
AMD’s Ryzen 7040-series (Phoenix) APU carries eight Zen 4 cores, Phoenix 2 only features six -- two high-performance Zen 4 cores, and four energy-efficient Zen 4c cores considerably smaller than their counterparts. This suggests that AMD will see the Phoenix 2 as a lower-cost APU for cheaper laptops.
If correct, AMD could challenge Intel’s Alder Lake and Raptor Lake laptop offerings. It should provide some good performance metrics at power levels previously unattainable. The Zen 4c and Phoenix 2 design should be much cheaper than the original Phoenix.
AMD’s codenamed Phoenix 2 processors were expected to hit the market this year but appear late. Toms thinks that they will not be around until the launch of the Ryzen 8000-series lineup set to arrive in 2024.
This will be bad news for AMD as it must match Intel’s entry-level Meteor Lake, which is projected to be considerably more competitive than the current offerings.
